LUCIAN ROSENWALD, or Kansas omnmlssonnr YJCOLLAVPSIBLE BOX.

To all whom it may concern:

Be it known that I, LUCIAN RosENwALD, a citizen of the United States, residing'at Kansas City, in the county of Jackson and I Y The object of my invention is to provide a collapsible box of novel construction, which is cheap, strong and durable, and which may be easily and quickly extended or collapsed by an inexperienced person.

The novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawing, which illustrates the preferred embodiment'of my Figure 1 is a perspective view of my im proved box shown extended and bottom side up. I

Fig. 2'is a cross section oftthe same.

Fig. 3 is a plan view of the bottom member with" the flaps horizontally disposed.

Fig. 4 i a plan view of the body of the box collapsed.

Fig. 5 isa plan View of the strip which forms the body prior to its being'formed.

Similar reference characters designate similar parts in the different views.

1 designates the body of the box, preferably formed from a rectangular strip of suitable material. such as sheet wood or card board, the ends of the strip being overlapped and secured together.) 7

The body is provided'with a plurality of transverse flexible joints 2, formed by scoring or creasing the material at right angles to the longitudinal edges of the strip 1. The said joints are located at the respective corners of the box, so that the body may be collapsed to the flat form, shown in Fig. 4, or extended to operative position, as shown in Figs. 1 and 2.

3 designates a bottom member, preferably in g cut away.

isofthe usual berry box form, substantially "rectangular, the

g corners of the rectangle be- I he bottom member is substantially rectangular and fitted in the bodyv 1, the corners of the bottom member being "extended through the openings 4 respectively, when the box is set up for use.

To permit of the easy. insertion or removal of the bottom'member 3, it is provided between opposite edges with a flexible joint 5 arranged. to permit the bottom member to be flexedupwardly but not downwardly,

from the horizontal along the joint.

Preferably the joint in the bottom memher is formed. by scoring the underside.

This permits of the upward flexingat the 'edgesrespectively with'flaps 6'fl'exib1y connected withthe bottom and adapted to be 'jointfrom'the horizontal. but does not perbent downwardly along or adjacentto said edges so asto .form legs. as shown in Figs. 1 and'2, thelower edges of the flaps, when so bent, being,'pr'eferably flush withthe lower edges of the body '1. These legs serve to stiffen the box, and those at the ends of the box, preferably disposed at opposite side of the joint 5. prevent the bottom member being flexed. downwardly at the joint.

Tohave the flaps flexibly connected with the bottom member, so as to be easily bent downwardly, the under side of the bottom member, adjacent to the places of joinder of theflaps, is provided, parallel with the adjacent edges of the bottom member, with scorings or creasings 7, disposed adjacent to said edges.

Theends of the strip 1 are preferably releasably secured to each other by some suitable means. In the drawing, Fig. 5, I have shown the strip 1 provided adjacent to its ends respectively. with two parallel slits 8 extending respectively from opposite longitudinal edges toward the adjacent ends and to a point half way between said edges.

In setting up or assembling the box, the strip 1 is bent to the proper form along the joint 2, after which the tongues 9, which are formed at the ends of the strip by the presence of the slots 8, are respectively slipped into the slits 8 of the opposite ends,

the tongues being preferably at the inner side of the box, with the slits 8 in alinement with each other, and with the longitudinal edge of the strip also disposed alinement with each other at both ends of the strip.

The body will thus have its ends securely and releasably held together, after wh ich I the bottom member 3 is bent upwardly along .the joint 5 and. inserted, With the flaps .6

serted in the openings 4 before-the ends of the strip 1 are joined.

I do not limit my invention-to thestructure shown and described, as modifications, within the scope of the appended claims, may be'made without departing from the spirit of my invention.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is w l. A collapsible box comprising a body consistingof va rectangular strip provided adjacent to its ends respectively with two parallel transverse slits which extend re spectively from opposite longitudinal edges obliquely toward the, adjacent ends and to points respectively half way between said edges, each end of the, strip being inserted through the slit which is adjacent to. the other end, the slits being disposed in alinement with each other, when the strip is bent to form the body, the strip having-trans verse flexible, joints at the. respective, corners, the body being provided, withlateral openings, and a bottom member adapted to be fitted in said body and adaptedto have its corners extend respectively through said openings.

2. A collapsible box comprising a body consisting of a rectangular strip having adjacent to its respective ends two parallel transverse slits which extend respectively from opposite longitudinal edges obliquely toward theadj-acent ends and to points respectively half way between said edges, each end of thestripbeinginsertedthrough theslitwhichis adjacent to -the other end, theslits being in alinement with each other whenthe strip is bent to, form the body, said endsbeing at the inner sideof the body, the

strip having transverse flexible joints atithe respective corners of the body, the body having lateral openings, and a bottom member adapted to be .fitted in said body and to have its corners extend respectively through said openings;

3. A collapsible box comprising a folding body having corner openings, and a bottom member adapted ;.to-- have its: corners respectively project through said openings, 1

the 'bottom' nember being provided with edge flaps extendingudownwardly and disposed at the inner side of fand located wholly within the, body and. forming legs therefor 4. A collapsible box-comprising-a fol-ding body, and a bottom member having a longitudinal. joint, and provided at, opposite sides respectively ofsaid joint with; downwardly extending portions which form legs fOr holding the; .bottom ;fro mbendingdownwardlyat its joint.

5. A collapsiblesbox icomprising a body, and a bottomniember having a joint extending from one edge to theoppositeledge,

and providedwith downwardly extending legs adapted to preventthe downward; flexurewof the bottom member' at said joint.

In testimonywhereof v I have signed; my

name to this specification in presence of two subscribing I witnesses.
